Thinking about eye surgery using a Lasik procedure is a big step, and many people are a little hesitant to ask the questions that they have. The Lasik procedure, though widely talked about, is not discussed in detail, and people tend to fear the unknown. This article addresses some of the more commonly held fears, and talks about the experience for the vast majority of people that undergo a Lasik procedure.
One of the most common fear, both when it comes to the Lasik surgery and any operation in general is the fear of pain during and after the surgery. When a Lasik surgery is performed the eye is applied with numbing drops. The patient also receives a mild sedative so they can relax and feel comfortable. So even though you may feel a minor pressure to the eye, it is relatively pain free
The surgeon does use a laser in the eye to help reshape the cornea during the Lasik procedure. Many folks are worried about the laser being shone directly into the eye, or that they might look away and, due to this, develop a serious complication with their eyes and the Lasik laser beam effects. In actuality, the laser is only active for ten to fifteen seconds for each eye, and the Lasik machine has a tracking system that allows the beam to be on only when the eye is in the correct position.
Another general fear for people contemplating a medical procedure is fear of “the scalpel”. Any Lasik procedure uses only a very small microkeratome blade to approach the eye, or some more recent Lasik innovations have the laser itself created the flap and avoid using any hard surface at all. There is no reason to be concerned about a scalpel, for the Lasik physician does not use one.
Many wonder about the horror stories they hear about this or any other operation, and wonder about serious consequences like going blind. According the government statistics taken by the FDA, there are no reported cases of blindness due to a Lasik operation.
Actually, the risk of a serious permanent complication due to the Lasik procedure is less than 1 percent, and the risk of any permanent complications even if not serious (such as light halos) is 3 percent or less. It is extremely rare for a patient to not have improved vision after a Lasik procedure.
If the fact that you are awake and your eyes are open during the operation bothers you, just remember that you are given a mild sedative and your eyes will be dripped with numbing drops.
Is it more the thought about the Lasik physician’s hand close to the eye that bothers you? Then just think about that your eyes will be applied with drops that make your vision black out for the ten to fifteen seconds the operation takes.

The most popular eye surgery today is LASIK surgery. It is efficient, fast, very gentle and with few complications. For most people the LASIK surgery can help them no matter if they are nearsighted, farsighted and have astigmatism.
LASIK technique is a further development of the older PRK laser surgery. Both operations are done by removing the outer cornea layer, so the laser can remove the tissue. The difference is that while the PRK eye surgery scrapes the outer layer of the cornea away, the LASIK surgery will cut a flap in the cornea that can bend. After the surgery the flap will be put back again.
The operation itself takes only a few minutes and is completely painless. The eye will be anaesthetized right before the surgery, and most people will not feel any pain at all. Subsequently the flap will be cut and the laser surgery can be made.
The actual operation only takes between 30 seconds and two minutes. A laser specially designed for operating in the eye’s sensitive tissues will be used. After the operation the flap is put back in place.
It is possible to leave the operating room right after the surgery. The eyes may sting a little bit, so it is advised to rest for the rest of the day. A nap can also help.
For most people the sight will have improved right after the operation. It will then stabilize over the next weeks.
After the eye surgery the eyes can feel a little dry. It is therefore recommended to drip them with a little salt water.
All studies indicate that a permanent sight improvement is provided by the LASIK operation. And previous bad eyesight will not return again. But a possible, natural change of sight in the future is not possible to prevent by the operation. So the surgery should not be done before the sight is stable.
The age-related long-sightedness that all people will experience can also not be prevented by a LASIK operation.

There are three different to use when doing eye surgery; all of them with almost the same name: LASIK, LASEK and LASAK. The three surgery methods can be combined with two extra methods to give an even better result. The names of the two treatments are: Wavefront and Aspheric.
LASIK is the most popular of the methods. It is fast, effective and gentle. And complications using this laser surgery method are very rare. For most people, LASIK surgery will be a good method to improve their sight.
LASIK surgery is almost painless, and the sight has improved only a few hours after the operation. The side effects are few; dry is the most common. LASIK can help most people; long-sightedness until +3 and near-sightedness until -12.
The other surgery method called LASEK (or E-LASIK or ELSA) is great for people, who are only a little near-sightedness or and long-sightedness (from -2 to +2).
Because the operation is made on the surface of the corneas, the LASEK surgery is especially good, if you have thin corneas. It is also better, if you suffer of dry eyes.
The newest type of laser surgery is called LASAK. The flap, which is cut off, is thinner than when doing LASIK surgery. That saves the corneal tissue and is therefore a better method for people with thin corneas.
Other advantages of the LASAK surgery are a shorter time of healing and lesser risk of complications. There is also no pain after the operation, and the eyes will not be so dry. Finally the sight is steadier.
To improve the result even further, the Wavefront treatment can be used in combination with all of the three laser surgery methods. A special instrument is used to measure the irregularities on the corneal, and a kind of topographic map is created. A computer makes a range of calculations, so the laser surgery is carried out for the specific eye.
With Wavefront the treatment will be unique, which gives a better result. The night sight will also be better. Finally astigmatism in the eyes will be corrected better.
Aspheric treatment is the newest step in eye surgery; and is used in combination with LASIK, LASEK and LASAK. The treatment takes into account that the cornea is not ball-shaped; but aspheric.
When using LASIK, LASEK or LASAK without Aspheric treatment, the eye will be more ball-shaped. That gives a reduced contrast ratio and a bad night sight. If the Aspheric treatment is used, the curve in the central part of the eye will be made larger (as it is in an untreated eye). This gives a much better result; sometimes even better than with contact lenses or glasses.
